And it’s somewhere on Planet Earth. Must have been near by Eden. Could not have been from South America. One people like to try discrediting the Bible because of some seemingly minor missing location. They never attack Eden. Just Nod. A great deal of Bible geography is known thanks to archeology. The locations of Cush and Put, Togarmah, Gomer, GOG/Magog, etc. are known. These place names are found in Genesis and other chapters. They are fact. Given that track record I think prudence is the better tact. Nod existed. Cain lived and died. Who were his offspring? What is the “mark of Cain”?
